2011 - 2014 TerraGator DEF Delete Tune

A TerraGator earns its keep hauling full loads of fertilizer across soft fields, and on the 2011 - 2014 models a DEF fault can cut that power without warning. These floaters use the AGCO Power 8.4L with e3 SCR, so the fix is in the software. The Reflash Master handheld reads and rewrites the ECM through the diagnostic port to turn the DEF system off, and Stage 1 or Stage 2 tuning adds up to 20% more power. We ship all across the US and Canada.

Why delete the DEF on a 2011 - 2014 TerraGator?

DEF

Diesel exhaust fluid

Floaters burn through a lot of fuel in a short season, and DEF use rises right along with it. That means another fluid to stock at the yard, keep from freezing in winter storage and top up between loads. On machines this age, the tank sender, pump and heated lines have also started to wear out, and each one can stop the dosing system. Turning DEF off in the ECM removes all of that upkeep.

SCR

Selective catalytic reduction

The e3 SCR system relies on its NOx sensors and dosing module reporting normal values. When one of them fails on a TerraGator, the engine can drop into reduced power with a full box of product and a field still to finish. Our file shuts off SCR monitoring, so those faults no longer slow the machine down.

Made for heavy flotation work

All three TerraGators run the same 8.4L engine, but each was rated for a different chassis and payload. Your calibration is built from the file read off your floater, so the result matches how it was set up from the factory.

01Pull through soft groundExtra torque helps the CVT hold ground speed with a loaded box in wet spots.
023-wheel or 4-wheelThe TG7300 and TG8300 three-wheelers and the TG8400 four-wheeler are all covered.
03Undo any timeThe original calibration is stored on the handheld if you ever need to go back.

Frequently asked questions

Q1Which TerraGator models does this cover?+

The 2011 - 2014 TG7300, TG8300 and TG8400 with the Tier 4i AGCO Power 8.4L engine. Newer B and C series TerraGators are sold under a separate listing.

Q2Is any exhaust work needed on my TerraGator?+

None. These floaters never had a DPF or EGR, and the SCR catalyst can stay on the machine. Only the ECM file changes.

Q3How do I deal with the DEF tank after the reflash?+

Drain the tank and push washer fluid through the pump and lines. That way no fluid is left to crystallize while the system sits unused.

Q4How much power can I expect?+

A TG8300 rated at 365 hp reaches about 402 hp with Stage 1 and about 438 hp with Stage 2. The TG7300 and TG8400 gain 10% and 20% from their own ratings.

Q5Can one handheld do more than one TerraGator?+

Yes. When you flash your first TerraGator, the Reflash Master locks to that machine’s VIN so the file can only be written to the floater it was built for. The handheld is yours to keep, so you are not buying a new device for the next one. Call or email us when you are ready and we will unlock it. Your next machine then goes through the same read, send and write steps with its own custom file, which is priced as a separate tune.

Q6When will my kit ship?+

Most orders leave our shop the next business day for delivery anywhere in the US or Canada. Expedited orders after 12 PM ET go out a day later.
